@Johnnyinsfca customers are able to review pros based on any interaction with them. So although they didn't hire you, they are able to leave you a review based on the meeting or conversation you had. Learn more here and let us know if you have any questions.
I have had a similar experience. The review was 1 star and the text was, "Just is". I looked at our messages. I sent her a quote. She hired someone else. That was it. No explanation. I asked her why the bad review. No response. Another left me a 2 star review. This one had no text. I have also reached out to the customer and get no response or explanation. It's really messed up.
